  • Patent number: 11123144
    Abstract: Apparatus, including a patient tracker, attached to a subject, having magnetic field sensors and optical landmarks with known spatial relationships to each other. A camera acquires a 3D optical image, in a first frame of reference (FOR), of the subject's face. A magnetic radiator assembly generates magnetic fields at the subject's head, thereby defining a second FOR. A processor: processes field sensor signals to acquire location coordinates of the sensors in the second FOR; segments a tomographic image of the subject, having a third FOR, to identify the subject's face in the third FOR; computes a first transformation between the third and first FORs to map the tomographic face image to the 3D optical image; maps the optical landmarks to the third FOR; maps the respective location coordinates of the sensors to the first FOR; and computes a second transformation between the second FOR and the third FOR.

  • Patent number: 11116420
    Abstract: Physicians performing invasive procedures utilize instruments inserted into a human body to perform the procedures. Such procedures typically involve actions to be performed on specific targeted anatomical structures. During the procedure, nearby anatomical structures unrelated to the procedure should generally be avoided. A system and techniques are provided herein for monitoring the position of such unrelated nearby anatomical structures relative to one or more surgical instruments. The system emits a warning to a human operator such as a surgeon if one of the instruments is too close to a monitored anatomical structure.

  • Patent number: 11103266
    Abstract: Variations of integral navigation controls may be used in conjunction with a medical instrument to provide navigation functions for an image guided surgery (IGS) system that is in communication with the integral navigation controls. In some variations, a medical instrument with integrated navigation wheels allows movement of a cursor of the IGS system along the x and y axis by scrolling the wheel, or allows selection, zooming, or other controls by combined clicking and/or scrolling of wheels, and may be sterilized or discarded along with the device. In some other variations, a control overlay may be temporarily attached to the medical instrument to provide additional controls, such as buttons or a pointing stick, and then removed and sterilized or discarded after a procedure. In each variation, inputs may be communicated via wire or wirelessly to an IGS system to provide navigation of images during a surgical procedure.

  • Patent number: 11058497
    Abstract: Physicians performing invasive procedures require accuracy and precision when working with surgical tools. Surgical procedures are increasingly becoming minimally invasive, with physicians operating using cameras to view the surgery site and directing their tools through oculars or video displays. Ideally, the physician should be able to perform the invasive procedure while simultaneously observing both the real-time image of the patient and additional data critical for his medical decisions about the manipulation of the surgical tool and the next surgical step. The augmented reality navigation system of the present disclosure provides tool location visibility for invasive procedures through the use of location sensors included on a camera and/or on the tools used during a procedure. A location tracking system determines and monitors the locations of the tools and camera based on the characteristics of signals detected by the sensors and displays informational overlays on images obtained with a camera.
